DKIM Alignment (adkim)

Relaxed (default)

SPF Alignment (aspf)

Relaxed (r)

Understanding alignment modes

DKIM Alignment (adkim)

Relaxed mode: The DKIM signature's domain can be a subdomain of the "From" header domain.

SPF Alignment (aspf)

Relaxed mode: The SPF "Return-Path" domain can be a subdomain of the "From" header domain.

Note: When alignment parameters are not specified, DMARC defaults to relaxed mode for both DKIM and SPF alignment.

Know when your DNS records change

The check you just ran shows your current configuration. But DNS records change, sometimes without you knowing. A well-meaning IT change, a third-party provider update, or an unauthorized modification can break your email delivery overnight.

Configuration Drift

IT changes that accidentally break authentication

Provider Updates

Third-party services changing their SPF includes

Unauthorized Changes

Attackers modifying records to send as you

DMARCTrust monitors your DNS records continuously. When something changes, you get an email alert with exactly what changed and why it matters. No more surprises when customers complain their emails bounced.

About This Checker

What we check

We analyze your domain's email authentication: DMARC policy and alignment, SPF record and includes, and BIMI logo/CV when present.

Why it matters

Healthy authentication improves delivery and blocks spoofing. Major inbox providers increasingly require DMARC and robust SPF/DKIM practices for senders.

Included features

  • DMARC syntax, policy, and reporting validation
  • SPF record evaluation and include analysis
  • DKIM/SPF alignment interpretation
  • BIMI record and VMC detection
  • Clear setup and remediation guidance
